Datasheet
Conguration Register
The configuration register allows the user to program
various DS75LV options such as conversion resolution,
thermostat fault tolerance, thermostat polarity, thermostat
operating mode, and shutdown mode. The configuration
register is arranged as shown in Figure 5 and detailed
descriptions of each bit are provided in Table 2. The user
has read/write access to all bits in the configuration reg-
ister except the MSb, which is a reserved read-only bit.
The entire register is volatile, and thus powers up in its
default state.
